I. Detailed Description: This includes scenarios, screenshots, vulnerability reproduction methods. For account-related vulnerabilities, please provide test accounts. If the reproduction process is complex, you may record a video, upload it to Taopan, and attach the link. 1. Install ms-swift 2. Start web-ui 3. After startup, access through browser at http://localhost:7860/ to see the launched fine-tuning framework program 4. Fill in necessary parameters In the LLM Training interface, fill in required parameters including Model id, Dataset Code. The --outputdir can be filled arbitrarily as it will be modified later through packet capture 5. Click Begin to start training. Capture packets and modify the parameter corresponding to --outputdir You can see the concatenated command being executed in the terminal where web-ui was started 6. Wait for the program to run (testing shows it requires at least 5 minutes), and you can observe the effect of command execution creating files II.…

# Patch Next advisory brief: CVE-2025-41419

Advisory: MS SWIFT WEB-UI RCE Vulnerability
IDs: CVE-2025-41419, GHSA-7c78-rm87-5673
Record: https://patchnext.com/advisories/cve-2025-41419 (revision 3, source checked 26 Oct 2026, 13:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: ms-swift 3.7.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI ms-swift: affected < 3.7.0; fixed in 3.7.0

## Suggested inspection (read-only)
- `python -m pip show ms-swift`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on ms-swift.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
